A pipe joint and elongated cementitious pipe is formed by joining abutting ends of adjacent pipe sections with a fiber reinforced composite material without the need for the pipe sections to have other connection means, such as the standard bell and spigot end connections. Also disclosed is a cementitious pipe including at least two cementitious pipe sections having ends that are joined together with a fiber reinforced polymer composite material. The cementitious pipe sections and resulting cementitious pipe may have a substantially uniform wall thickness and substantially uniform inner and outer diameters near the opposite ends of the pipe sections. Also provided is a method for joining cementitious pipe sections with a fiber reinforced composite material to manufacture an elongated cementitious pipe, such as an elongated concrete pipe.

A sealing profile for embedding into a moulding of curable material, in particular a concrete or plastic moulding, and to a sealing arrangement comprising such a sealing profile. The object of the present invention is to provide a sealing profile for embedding into a moulding of curable material that can be anchored into the moulding in particular such that displacements of the seal in its seat occur to a significantly lesser extent, if at all, when installing or assembling the mouldings. The object is achieved by a sealing profile (1) with a profile region (2) having a profile region surface (4) which is directed towards the moulding (3) after embedding the sealing profile (1), wherein the profile region (2) has, at least in one subregion (6), a non-woven, felted or random fibre layer (5) which is fixedly connected to the sealing profile (1) and which extend beyond the profile region surface (4).

An integrated jacking pipe comprising a concrete jacking envelope integrally-formed with and encircling a metal pipe, wherein said metal pipe comprises a spigot protruding from said concrete jacking envelope and a bell whose diameter is larger than a diameter of said spigot.

A fiber reinforced polymer composite joining member for joining sections of pipe together to form an elongated pipe is disclosed. A pipe joint and elongated pipe includes at least two pipe sections having ends that are joined together with the joining member is also disclosed. The pipe joint and elongated pipe are formed by joining abutting ends of adjacent pipe sections with the joining member without the need for the adjacent pipe sections to have other connection means, such as standard bell and spigot end connections. Also provided is a method for joining pipe sections with the joining member to make an elongated pipe.

A prefabricated part comprises a concrete body that has the form of a pipe section with two pipe ends and a pipe inner side. The pipe inner side is lined at least in some areas by a lining made of plastic material connected to the concrete body, and at least one of the pipe ends is covered at least in some areas by a molded part made of plastic material connected to the concrete body. At least the pipe end, which is covered at least in some areas, has a connecting joint in order to connect the pipe end to a pipe end of a further prefabricated part. The lining consists of a thermoplastic material and the molded part consists of a thermosetting plastic. The lining and the molded part are connected to each other in a sealed manner.

The invention relates to a plug connection between two tubular workpieces (1, 2) which are made of concrete and each of which has an inner liner (5) made of plastic, one of which forms a tip end (3) and the other a socket end (4) receiving the tip end (3), wherein the inner liners (5) have circumferential sealing flanges (12) which cover the end face (13) of the tip end (3) or the socket face (14) and wherein a joint seal (16) is provided between the sealing flanges (12). In order to provide advantageous structural conditions, it is proposed that the inner liners (5) are provided with a circumferential elastomer angled profiled section (8, 9) at the end face, which receives the circumferential edge of the inner liner (5) in an end-face profiled groove (11) of its axially parallel limb (10) and whose limb at a right angle to the axis forms the sealing flange (12).

Structural body comprises a concrete core and a cap around the opening. A first wrap is wrapped under tension around the concrete core and a portion of the cap to form a continuous water resistant barrier around the outer surface of the concrete core. A second wrap can be wrapped under tension around the inner surface of concrete core to form a continuous water resistant barrier around the inner surface of the concrete core. Structural body can be formed as a pipe with a male and female ends to interconnect multiple pipes. The joint formed between two structural bodies has a continuous water resistant barrier that prevents the environment from contacting the concrete core.
